Application filed November 27, 1915. Serial No. 63,894.

To all whom it may concern:

Be it known that I, JOHN. F. LewsoN of rality of die-beds on each of two pairs of.

rotary disks, the die-beds of one pair of disks being adapted to cooperate with the die-beds of the other pair of disks. The die beds are controlled by cams, so that when two opposed die beds approach a cooperative position they are approximately par allel. As the two are brought closer together by the rotation of their supporting disks, their parallelism is accurately main-7 tained by means of telescoping parts rigidly secured to said die-beds of their journals. Means are provided for adjusting the relative position of the two pairs of disks with their die beds and for feeding the work between the die beds. 1

The whole is constructed as hereinafter more specifically described and as illustrated in the accompanying drawings in which.

Figure 1 is a side elevation ofthe machine; Fig. 2 is a side elevation partly'in section; and Fig. 3 an end elevation.

In the drawings like numerals'of reference indicate corresponding parts in the different figures.

1 is the frame of the apparatus suitably shaped to support the different parts. On this frame are carried two rotarysupports on which diebeds are journaled. Each support preferably comprises a pair of disks 2 connected by :a shaft 3. The shaft for the lower support is journaled in any suitable manner on the frame of the apparatus. The shaft 3 of the upper support is journaled in boxes 4 vertically movable in the guides 5 formed in theframe of the machine. Each box is vertically adjustable by means of a screw 6 threaded through the nut 7 secured to the'top of the frame. The

' screws 6 must be so connected to the boxes that the screws will rotate freely and will be heldfrom longitudinal movement relarotate.

- tive to the boxes, and thus the boxes may be held in any suitable vertical position to adanother.

just the die bed supports relative to one The diebeds 8 are journaled in the disks so that the die beds may be moved to maintain a substantially parallel position when in cooperative relationship. The die beds are actuated by means of the cams 9, which are provided withsultable cam grooves with which crank arms 10 connected to the jourr,

nals of the die beds are adaptedv to engage.

These cams bring cooperative die beds into substantial parallelism as they approachv one-another, and this parallelism is accu rately maintained by telescopic means con nected with the die beds themselves. For this purpose I providethe die beds at one or both ends with telescopic means comprising the'tube 11 connected to the journal of one of the die beds and a pin 12 connected to-the journal of the opposed or cooperating die bed. The pinenters the tube and thus the beds are held accurately in parallelism whilethey are free toapproach and retreat from one another as the supporting means The die beds may carry punches,

forming dies, shears or the like. From this constructionit is evident that the work may be operated on while traveling through the machine, thus effecting great saving in time. The pressure of thedies may be accurately regulated by means of the screws 6.

The die bed supports may be actuated in synchronism byany suitable means. I' show 7 the shaft 3 ofeach support provided with a worm wheel 13 withwhich mesh the worms 14 on the vertical shaft 15.

This shaft is actuated by means of bevel gearing 16 from the main shaft 17, which may be actuated in any suitable manner. The driving gear may i ,be duplicated at the opposite side of the machine if necessary. V a v I provide an automat c feedfor the work arranged in the manner. I will nowdescribe.

Pairs of feed rolls 18 are provided both in front of and behind the die bed supports. These feed rolls are constructed arranged in the ordinary manner and are actuated by'the gearing 19 through theme-- dium of which the rolls of each pair operate simultaneously. With the lower gear 19 of each pair'meshes a gear wheel :20. These gear wheels 20 are secured to spindles 21 suitably j ournaled on the frame-of the maand chine and carry the sprocketwheels 22, on I which are carried the sprocket chain 23,.

which serves as amedium for actuating the feed rolls. Tins sprocket chain is intermittently actuated by means of the pins 2i carried by the lower die beds 8. lhese pins It should be stated that the lower cam 9 is preferably secured to the frame of the machine, while the upper cam 9; as it must be vertically movable with the support of the die beds in order to maintain its proper relationshipto the latter, is preferably se cured to the journal box 4.

What I claim as my invention is 1. The combination of two rotary sup- )ortin means; cob aeratin die beds 'ournaled one on each of the supporting means eccentric to the axis thereof; means for moving saidbeds into substantial parallelism when brought-by the rotation 01" their supports into cobperative position; and telescopic alining means connected part with each die-bed adapted to engage to hold the die beds in accurate parallel-ism while they are in cooperative position.

2. The combination of two rotary supportingmeans; cohperating die be 0 journaled. one on each of the supportir neans eccentric to the axis thereof; means for moving said beds into substantial parallel: ism when brought by the rotation of their supports into cofiiperative position; telescop1o aiming means connected part Vltl) each die-bed adapted to engage to hold the die-beds in accurate parallelism while they are 111 cooperative position; and means for varying the distance between. the axes of the supporting means.
